The latest blog post in our current series looks at a topic we hope will be of serious interest to our Stevenage clients; the most common reasons why cars fail MOTs. By identifying the main reasons for MOT testing failures, you will be more aware of what to look out for and will build a better understanding of how to prepare for a test so that your car passes at the first attempt.
In addition to undertaking Class IV MOTs ourselves, we are also happy to help Stevenage motorists with MOT preparation and any repairs their cars might require for ensuring a certified road safe and road legal vehicle. Book in and save money over fast-fit centre and national garage prices by calling S. Keene Autos. You can contact us on 01438 362 234 or 01438 222 255.
Lights – It is estimated that 17% of failed MOTs are due to faulty brake lights, headlights, and the indicators. This category includes poor headlight aim. Lights are checked during car servicing, but we also recommend that from time to time, you have a household member stand outside your vehicle while you test each light. Should one not work properly, please visit our garage in Stevenage.
Malfunctioning lights aren’t something to be ignored because of the law and the wider interests of road safety.
Tyres – Around 14% of MOTs result in failure due to low tyre tread depth or previously unnoticed structural damage. A tyre requires 1.6mm of depth to be deemed road legal. Keep the drastically increased stopping distances that low (but technically legal) depths can cause in mind. It is usually worth replacing tyres before you are required to. This ensures safer stopping distances in cold and wet weather conditions around Stevenage.
Like your lights, your tyres will be checked over during car servicing.
Registration Plate – The same proportion of failed MOTs (14%) can be attributed to registration plate issues. Plates need to be perfectly readable in all conditions. Damage, or a faulty registration plate light, will both be issues which require a remedy. Also, avoid using customised plates on your vehicle. While 3D and 4D plates aren’t technically illegal, they must still comply with BS AU 145e (2021). Illegal registrations plates are one of the most common reasons for the police pulling over motorists in the United Kingdom.
Windscreens & Wipers – Many cars fail MOTs due to the driver’s view of the road being obscured. One thing that plays a part in this issue is the condition of your windscreen and wipers. Damage to the latter isn’t deemed to be acceptable wear and tear. With the former, chips and cracks in a place that obscures the driver’s vision will lead to a test failure.
For this reason, we urge Stevenage motorists to visit us for car repairs and to have them completed well ahead of their next MOT appointment.
Brakes – Your braking system has an essential role to play in keeping you safe on the road. Failed MOTs will be the least of your worries if you experience any difficulties with braking when driving. Worn brake pads, discs, drums and shoes should be immediately addressed by a trained mechanic, like those found at S. Keene Autos of Stevenage, well before MOTs are due.
